Pike construction



March 25, 1930. E. c. LEACH PIKE CONSTRUCTION Filed April 13, 1928 Patented Mar. 25, 1930 UNETED STATES PATENT OFFICE ELBERT C. LEAGH, F OSHKOSI-I, VJISCONSIN, ASSIGNOR TD LEACH COMTPANY, 0F OSHKOSH, WISCONSIN, A CORPORATION OF WISCONSIN PIKE CONSTRUCTION Application filed April 13,

The principal object of the invention is to provide a pike of improved construction.

Other objects and advantages of the invention will be evident upon a full understanda ing of the formation and arrangement of the diflerent portions of the pike.

In the accompanying drawing:

Fig. 1 is a side view of the pike;

Fig. 2 is a different side view of the pike; and

Fig. 3 is an end view of the pike.

As will be observed in the drawing, the pike is an elongated one-piece forging which is provided intermediate its ends with a radially extending annular flange 10. The front portion 11 of the pike is swedged abruptly down into the form of a cylinder adjacent the flange 10, and is squared, tapered and twisted a quarter of a turn adjacent the front tip. The rear end portion 12, like the front end portion 11, is swedged down abruptly into the form of a cylinder adjacent the flange 10, and is squared and tapered, but not twisted, adjacent the rear tip.

The rear end portion 12 of the pike is adapted to be driven into a hole in the center of the end of a pole 13 sufficiently far to bring the flange against the end face of the pole, all as shown in dotted lines in Figs. 1 and 2, and that part of the pole which extends from the end face to a point approximately opposite the rear tip of the pike is preferably reinforced by a sleeve 14, against which the flange 10 may advantageously hear.

The front'tip of the pike presents a screwlike formation which causes the pike to h old fast in anything into which stuck, although the pike can be easily disengaged by a slight twisting or unscrewing movement of the same. The flange 10 presents an abrupt shoulder which will eflectively limit the eX- tent to which the pike will pierce soft material. By forming the flange 10 as an integral part of the front and rear end portions an 1928. Serial No. 269,727.

extremely strong and inexpensive construction is obtained.

I claim:

1. A pike for application to the end of a wooden pole, consisting of a one-piece metal member having a radially extending annular thrust flange an elongated rear end portion which is considerably smaller in diameter than the flange and merges abruptly thereinto and is tapered at its extremity for forced fit insertion within an aperture in the end of a pole to a point where the flange is brought into engagement with the end face of the pole, and an elongated front end portion which is also considerably smaller in diameter than theflange and merges abruptly thereinto and is faced and tapered to present a work-engaging tip.

2. In a device of the character described, the combination with a wooden pole, of a pike at one end of the same consisting of a onepiece metal member having a long spikeshaped inner end which is forced into a central aperture in the end of the pole, a long spike-shaped outer end which projects axially from the end of the pole, and interposed radially extending flange of considerably greater diameter than the bases of the pike ends, said flange presenting abrupt opposite- 1y facing annular shoulders about the bases of the pike ends, the shoulder about the base of the inner end engaging with the apertured end of the pole to protect such end against. splintering and prevent the pike from being forced farther into the same under impact with the work, and the shoulder about the base of the outer end forming a hilt which will limit the extent of penetration of the pike into soft work.

3. The combination with a wooden pole having an aperture in one end thereof, of a pike for application to the pole, comprising a one-piece metal member having a radially extending annular thrust flange which substantially covers the apertured end. of the pole in flat engagement therewith, an elongated rear end portion which is considerably smaller in diameter than the flange and projects abruptly therefrom and is tapered at its extremity for forced fit insertion in the aper ture in the pole, and an elongated front end portion which is also considerably smaller in diameter than the flange and projects abruptly therefrom and is tapered to present a Work-engaging tip.

In testimony whereof I have hereunto subscribed my name.

ELBERT C. LEACH.
